Districts Impacted
Project Summary
The Missouri Route 3 bridge in Armstrong over CPKC Railroad in Howard County, is slated for replacement in 2027 or 2028, dependent on contractor scheduling. Built in 1941, the bridge is in poor condition and showing signs it has reached the end of its useful life.
Construction of a new bridge will require a full roadway closure. A signed detour will direct motorists to use Missouri Route 240, 5, 3, and Howard County Route V.
PUBLIC MEETING
An in-person public meeting will be held on Thursday, Sept. 3, 2026, at the Armstrong City Hall from 4:30 to 6 p.m. Members of the project team will be on hand to provide information and answer questions from the community. There will be no formal presentation, so members of the public can come and go as they please. By participating and commenting, the public can help MoDOT determine the design and construction plan that best serves the needs of the roughly 1,800 motorists who use the bridge on an average day, while being responsible stewards of available funding.

Project Progress
The Missouri Department of Transportation is in the process of designing a new bridge on Missouri Route 3 bridge over CPKC railroad in Howard County. The new bridge will be 28 feet wide, the same width as the existing structure. The project also includes new approach pavement, barriers, pavement marking, and raising the bridge to meet current railroad requirement.
This project is not expected to require new right-of-way acquisition.
The estimated total cost (engineering, and construction) for this project is $5.9 million. This cost may change.
During the three-week comment period running Aug. 27 – Sept. 17, 2026, the community and interested parties will have multiple avenues to learn about, ask questions, and submit input regarding the planned work and associated traffic impacts.

That is the earliest date the contractor may begin work.
Construction is expected to take place in 2027 or 2028, dependent on contractor scheduling. The roadway is expected to close up to 180 days, subject to change.
